Proposal and Simulation for Asynchronous High Quality Local Positioning and Posturing System (LPPS)

Abstract

Mobile robots are recently being used in various environments. Since errors in position and posture occur while operating the mobile robots in these environments, positioning and posturing are very important. Several researches are currently under progress for these corrections. For example, we often use sensors such as accelerometer, the Cooperative Positioning System (CPS), or the Global Positioning System (GPS). In our research, we propose a method using a 2.4[GHz] specific small power microwave. In our method, we consider that the most important aspect is phase synchronization between transmitters and between transmitter and receivers. However, the proposed system does not require this synchronization. Therefore, our system has a simple structure, high quality and easy upgradeability. We simulate this Local Positioning and Posturing System (LPPS) and examine the results.
